Tire tread



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the tread pattern repeats circumferentially throughout the outer circumference and shoulder of a tire;

FIG. 2 is a front elevation view thereof; and,

FIG. 3 is a right side elevation view thereof.

In the drawings, the dark stippled surface shading represents the recessed groove portions of the tire tread having a depth as best illustrated along the top and bottom edges of FIG. 2. In the drawings, the broken lines defining the sidewall and inner bead depict environmental subject matter that forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
